Application filed April 13. 1907- Serial No. 367.931-

T all whom it may concern:

Be it known that I, J on RoYnEN PEIRoE, a citizen of the United States,residing in the borough of Manhattan, pity, county, and State of NewYork, have invented certain new and useful Improvements in Lathes forMarble or the Like, of which j the following is; a specification.

-' move longitudinally along ferent points in Myinvention aims toprovide an apparatus for cheaply and expeditiously turnin marble andsimilar building or ornamental stone, and for working columns or thelike turned out of such stone.

The marble is held between end chucks and rotated in engagement withroundin cutters to bring it to the desired rounde contour, and which aremoved longitudinall so as to turn the entire length 'of the ,wor therounding cutters being preferably moved automatically in a transversedirection. simultaneously with their forward movement so as to vary thediameter at difthe length of the column. Preferably also these cuttersare manually adjustable so as to produce a determined diameter at anydesired point in their longitudinal travel.

Preferably fluting cutters are arranged to the side of the column and tobe simultaneously and auto matically moved transversely to follow orproduce the longitudinal contour desired, and to be adjusted for anydesired diameter at a given point. Generally the work will be rotatedwhile the rounding cutters are in op eration, and will be stationarywhile the fluting cutters are in operation. While the rounding cuttersare in use the fiuting cutters will ordinarily be moved be ond an end ofthe column so as to be out of t e way; and the rounding cutters will besimilarly moved out of the way during the fluting operation.

The rounding cuttersare preferably rapidly rotating carborundum wheelshaving their axes parallel with the axis of the column. Theflutingcutters are preferably similar wheels but with rounded edges, andhaving their axes perpendicular to the axis of the column.

Various features of im rovement are referred to in dctailhereina 'ter.

The accompanying drawings illustrate an embodiment of the invention:

Figure 1 is aplan of the entire machine with its central portionomitted; Fig. 2 is a side elevation; Fig. 3 is an end elevation; Fig. 3is a sectional detail; Fig. 4 is a section approximately on the line 4-4of Fi 1 Fig. 5 is a section approximately on the line 5 of Fig. 1; Fig.6 is a plan partly in section of the device for communicating thedesired transverse movement to the carriages; Fig. 7 is a longitudinalsection thereof; Fig. 7 is a section of the valve, omitting its piston;Fig. 8 is a section on the line 8-8 of Fig. 6; Fig. 9 is a section onthe line 99 of Fig. 7; Fig. 10 is a diagram of a transverse-movementmechanism; Fig. 11 is a perspective view of the pneumatic mechanismcontrolling rotation of the work and the longitudinal feed of thecarriages. Fig. 12 is a diagram of the valve mechanism. Fig. 13 is asectional detail of part of Fi 12.

Referring to the emboc iment of the invention illustrated, the work A isheld between the two end chucks B and O. The machine may be one sided,that is to say, it may have a single rounding cutter and a singlefluting cutter, these two being arranged either upon thesame side of thework, or upon opposite sides. Or one cutter of eachtype may be arrangedat each side of the work, as, for example, the rounding cutters D, Dwith flat edges and consisting of carborundum wheels mounted on shaftsparallel with the axis of the work, and the carborundum fluting wheelsE, E of any desired contour on their edges and arranged with theirshafts vertical or otherwise transverse to-the axis of the work. Thecutters of any pair as D or E, E may be of the same material andfineness so as to merel double the rapidity with which the work 18completed, or they maybe of different materials and finenesses, one acoarse roughing wheel for example, and the other a fine finishing wheel.

The respective wheels are carried on carriages F, F, G, G arranged tomove in a longitudinal direction-(that is, parallel with the axis of thework,) upon beds H, the bases J of the carriages being arranged to slideu on the beds as in the manner indicated in "i s. 4 and 5. Thelongitudinal movement 0? the carriages is cilected by means of wormshafts K resting upon supports K at intervafls and engaging nuts L whichare held in bolts M fastening any particular nut L in drawn to such aposition as to avoid interference with the carriage F. In the withdrawnposition the carriage G will be detached from the shaft K and thecarriage F put into conneetion therewith.

- The main driving shaft N operates the cross shaft 0 which, b means ofa worm gear, drives the shafts The main shaft also drives a verticalshaft P (Fig. 3) which is connected by a worm with a disk Q This disk isfast on the shaft R of the chuck B. A segmental-block or lug S, theoutline of which is indicated in dotted lines in Fig. 3 is provided withbolt holes U registering with curved slots T in the disk Q so that bymeans of a bolt passing into one or other of the bolt holes U andthrough the slots T, the shaft may be firmly clamped at any desiredangle of adjustment. Friction clutches for the shafts O and P areindicated diagrammatically at O, O and P so that they may be reversed ordisconnected from the main shaft N at will. The support or bearing blockV for the shaft R is preferably fixed u on the base of the machine. Inorder to a apt the machine-for Work of less length, the bearing block Wfor the chuck C is made longitudinally adjustable along rails X, beingfastened in any desired position of adjustment by means of bolts Y; niceadjustments of the distance being effected by means of a screw shaft Zwhich controls the position of the chuck in its bearing. 7

A convenient means of rotating the carborundum wheels is by using aseparate 1no-' tor for each wheel and mounting it 'directly on thecarriage of such wheel so as to be adapted to operate it in allpositions. For

example, on the carriages F, F there are mounted electric motors a withhorizontal shafts and belt pulleys 1) driving belt pulleys c on theshafts of the wheels. Each of the motors is substantially inclosed by atop plate to keep out the dust, a hand-hole plate d being preferablyprovidedover each of the pulleys 0 (lower part of Fig. 1) so as topermit ready access thereto for applying or adjusting the belt, oilingetc.

The fluting wheels have motors e with vertical axes and belt pulleys ffor driving pulleys g on the vertical shafts of the cutters. The partsin this case are also protected by a surrounding casing, the casing foreach carriage being cut away at the back and some distance over the topto permit access to the motors and other mechanisms carried on thecarriages. A hand-hole plate 71. (Fig. 4) gives access'to the pulley onthe shaft of the uting cutter. .Hoods of any desired construction arearranged to protect the operator from the several wheels, such, forexample, as the hoods ;i .for the rounding outters and k for the fiutingcutters. N ozzls Z may be arranged at suitable points to supply waterjtoany or all of the cutting wheels. A platform m may he detachablyconnected to the base of the carriage F from which the operator may haveconvenient access to the controlling'mechani'sm hereinafter described,and a similar platform me be provided for the carriage G, these platorms being made detachable so asv to economize space by re moving themwhen their res ective carriages are at the ends of the machine and outof use.

Very few columns are made with their surfaces truly cylindrical. Usuallythey are of somewhat greater diameter between the ends than at the ends.With this machine theyare automatically shaped to any desired diameterat each point in their length, the shaping being effected preferably bytransverse movements of the carriages. For this purpose the base J ofeach carriage is pro vided with rails n extending transversely and uponthese slides an upper base 0 of the carriage, the motor and othermechanisms being mounteddirectly upon this upper base. The transversemovement may be effected by various types of mechanism. I. have shown inconnection with the rounding outters a mechanical device for effectingthe movements, and which is controlled by fluid pressure. In connectionwith the fluting cutters I have shown a fluid-pressure mechanism whichdirectly effects the movements of the carriages. Either or any othersuitable mechanism maybe used for the purpose.

Referring first to the carriages F, F, there are provided on the bages Jsuitable bearings p for the outer ends of short shafts 9 whose innerends are threaded and pass through nuts 1' upon the inner side walls ofthe carriages. Preferably a pair of shafts g is used for each carriageand, being arranged a substantial distance apart and working synchronously, they maintain the carriage in corrcct line so as to insure itssliding easily in its transverse movement. Passing through the bearingblock 7) are short longitudinal shafts I endwise beyond the range of thework. The

, and F" inward or outward simultaneously and to the same extent (theshaft 25 sliding through its pinion as shown in Fig. 1).

Means are provided whereby at each point in their longitudinal travelthe carriage's F, F take a determined lateral position. At one side ofthe machine, preferably the side opposite the operator, there isarranged. a uide preferably in the form of a thinimeta blade 2 extendinglongitudinall and adapted to be given a shape correspon ing to thedesired contour of the column by means of a series of hand screws 2 atshort intervals, connected to the flexible guide and screwin through arigid supporting bar 3.

Upon t e uide 2 there is a slide4 which partakes 0 the longitudinalmovement of the carriage F and is transversely moved according to thecontour of the guide, and whichby its transverse movements controls theoperation'of the fluid motor. at. A valve casing15- is mountedupon theslide 4 and moves therewith upon a valve stem connectedwith a sleeve 6,whichis set on the rod7. The relative positions of the valve casing andstem determine the admission of fluid to the motor a; and so determinethe operation of the shaft s as hereinafter described more fully. Inorder 'to utilize the power of the motor LB without shifting the slide 4and valve casing 5, the rod 7 may be operatedby hand. I made to extendacross to the operators side of the machine as indicated best in Fig. 5and is feathered through a inion 8 fixedly mounted on the carriage P andenga ing a pinion 9 on the lower end of a vertical shaft 10 carrying atits upper end a hand wheel 11 wit-hin'easy reach of the operator. Therod Zis also threaded through a nut 12 fixed on the side of the carriageF. This nut ordinarily; preventslongitudinal movement of .the rod so asto make the movements of the valve easing effective and, when the casingis 1 held stationary, ermits longitudinal movement of the rod iiyrotating the hand wheel 11 and thus permits an operation of the valvewhich controls the admission of fluid to the motor In connection withthe carriages G and G there is a similar slide 4 carrying a valve casing5 which has a reciprocating valve rod connected by an arm to the sleeve6 ordinarily fixed on the rod 7 particularly to Figs. 6 to 9.

For this purpose it is which, in this case, is rotatable but fixedagainst longitudinal motion to the carriage .1. The carriages G, G aretransversely moved by piston rods 13, one at each of the op osite sidesof each carriage and entering .cyinders 14. the valves of which arecontrolled similarly to the valves 5; that is to say, there is upon eachof the carriages G, G carrying the cylinders 14, a valve casing 15(similar to that of the valve 5), which valve moves with the carriageand the cylinder, and the valve rod of which is connected to a sleeve 16threaded on a shaft 17 extending transversely across the machine andcommon to the two carriages. The valve 5 controls the admission andexhaust from a fluid-pressure motor, preferably an air motor 18 so as torotate the shaft Win one or theother direction as desired so as to shiftthe rods ofthe valves 15 and regulate the admission of the pressurefluid, preferably water on account of its rigidity, to the cylinders 14.movement of the carriages without longitudinal movement, the shaft 7 ismade operable by hand through a pinion 19 thereon engaged with a gear 20upon a shaft 21 running across to the carriage G where it is featheredthrough a pinion 22 fixed upon the carriage and engagin a pinion 23 uponthe lower end of the vertical shaft 24 which carries at its upper end ahand wheel 25 within easy reach of the operator.

Returning now to the specific construction of the controlling air valve,reference is made The flexible supply pipes are omitted for clearness.The guide 2 preferably runs between rollers 26, 27, the latter of whichis carried by a air of plates 28, 29, the latter adapted to e adjustedin a slot in .the main slide 4 and clamped at any desired point therein.The slide 4 rests upon a suitable extension of the upper base 0 ofthecarriage, being free to slide in a transverse direction thereon andcarries on its upper face the valve casing 5.

The valve may be of the double piston tylpev Y indicated and connectedto the sleeve 6 an arm 30 upon which the valve rod 31 is adjustablyconnected. The rod 7 is adjustable and held by set screws as shown uponan intermediate sleeve 32 which has shoulders engaging the sleeve 6 sothat the latter partakes of the reciprocating move-' ments of the rod 7,the-sleeve 6 bei g held down upon the slide 4 by means of bo ts 33passing freely through slots in flanges of the il eeve. The set-screwsare indicated at 32,

Referring now to Fig. 10, and supposing G to represent a carriage ofwhich the hydraulic cylinder is represented at 14 and the piston rod 13,and supposing that the intermediate compressed air valve operatingmechanism is eliminated and that a shifting For effecting a transverseof the valverod 3 1 to the right admits water to the righthand side ofthe cylinder 14 and discharges it from the lefthand side, and that arelative movement of the valve rod in the posite'direction produces anopposite flow oi the water, then when the guide 2 moves inward andpushes the valve casing 5 inward, it will also move the carriage Ginward which movement of the carriage will cause a corresponding inwardmovement of the valve rod 31 (by ulling the rod 7' and sleeve 6, Fig. 1)whic will bring the valve back to the starting position with all portsclosed, and'- will hold the carria -e stationary in the position towhich it has been moved.

The opposite carriage G moves with the carriage G inward or outward.Similarly if the valve rod 31 be moved by hand say to the left bysuitably rotatin the shaft 17 and gears 19 and 20 and ro 7, the valvewill cause a movement of the carriage to the right sufiicient to carrythe valve rod back to its starting point relatively to the valve casing.

The carriages F and G are provided not only with the hand wheels 1 1 and25 for controlling the lateral positions of the carriages, but also withelectric switches 34 for starting or stopping the cutters and withvalves 35, 36 for controlling the rotation of the work and thelongitudinal travel of the carriages. The several hand operatedcontrollers described are arranged Within eas Y reach of an operatorstanding on one of t e two platforms m which are attached to the corre--spending carriages and travel with the carriages. They may, for example,be bolted to the carriages by means of straps, the unbolting of whichpermits the ready removal of the platform and that. carriage which isout of use.

The internal construction of the valves 35 and 36 may be considerablyvaried. In Fig. 11 they connect with flexible hose 37, 38, which carrythe necessary number of tubes to connect with the ports of the valves.For example, 35 is a 3-way valve as indicated in Fig. 12 and hasconnections with a pressure pipe 39 and with an outlet passa e indicatedby 40, and with a service pipe 41 eading into the upper end of acylinder 42, the piston rod 43 of whichoperates an arm 44 upon arockingshaft 45 whichhas at its opposite end a corresponding arm 46 forraising and lowering the clutch member P. The cylinder 42 is of the typeusual in connection with compressed air, the piston being moveddownwardly by the air when pressure is applied, or upward by a springwhen the pressure is withdrawn. The valve 35 therefore controls theoperation of the vertical rod P at the end of the .lever which rotatesthe work or holds it stationary. The valve 36 may be a 4-way valve witha pressure inlet 47 and outlet 48, and a pair of branches 49 leadingring in combination means or engaging the 180 senses to the ends ofcylinders 50 which control the o eration of the clutches O, The c utchesmay be operated similarly either from the carriage F or from thecarriage G.

Although I have described with great particularity of detail certainspecific embodiments of the invention, yet it is not to be understoodtherefrom that the invention is restricted to the specific embodimentdisclosed. Various modifications thereofin detail and in the arrangementand combination of the parts may be made by those skilled in the artwithout departure from the inventlon.
